EXHAUST GAS INLET STRUCTURE OF ABSORPTION COLUMN

WIPO Patent Application WO/2020/218240

A1

According to the present invention, an exhaust gas inlet 4 is provided to a side wall of an absorption column, and an inlet flue 1 is connected to the exhaust gas inlet 4. The exhaust gas from a combustion device passes through the inlet flue 1 and flows from the exhaust gas inlet 4 into the absorption column. A lower end edge 21 of the exhaust gas inlet 4 extends in a curve in substantially the horizontal direction. A bottom surface 17 of the inlet flue 1 has a flat main bottom surface 22 and a connecting bottom surface 23 that connects a downstream end edge 24 of the main bottom surface 22 and the lower end edge 21 of the exhaust gas inlet 4. The downstream end edge 24 of the main bottom surface 22 extends linearly in substantially the horizontal direction above the lower end edge 21 of the exhaust gas inlet 4. The connecting bottom surface 23 is configured by being divided into a plurality of surfaces, and each of the plurality of surfaces is any of downward sloping surfaces 27, 28, the exhaust gas inlet 4 sides of which are lower than the main bottom surface 22 sides, and a substantially flat surface 25.
